MikeHalloran, regarding your last post, do you mean "carries as much AXIAL load as the lower bearing" (i.e. along the axle).
And about the way a helicopter shaft is mounted, all the weight of the helicopter and axial rotor forces are on the bearings themselves... I thought I wanted to avoid...
To make things clearer, the problem is to mount a freely rotating shaft very firmly to a chassis, with the top end free, like in a helicopter. The shaft should be able to mechanically withstand axial forces and also be laterally secured, but rotationally free, of course.
Thank you for all your...
jistre, Thanks for that tip. I could use a thrust bearing at the base and plain bearings for shaft suppport. But then axial forces would only be held in one direction. Mounting a thrust bearing at the top is not an option since it is to be free, like the shaft of a helicopter.
A possibility...
Thank you for your answers, so the problems I had must have stemmed from different tolerances on the 6 mm bearing and shaft not making me able to simply press it on.
And my other concern about a bearings inner ring slipping radially at acceleration of the shaft, I conclude from your answers is...
Your suggested way of mounting would not hold it tight against even moderate torque.
The bearing I mounted using heat and very light hammering on the inner ring works fine, what I am asking for is a modular way of attaching bearings firmly. I found a product called ShaftLoc that does just that...
How do you attach a ball bearing to an axle. I have a 6 mm shaft and a 6 mm bearing and I have successfully mounted it by heating the steel bearing to a few hundred degrees and lightly hammering it into place.
But what I would like is some more modular way of attaching it, and how would I mount...
